Abstract

Aim: In contrast to significant advances in organ preservation in locally advanced rectal cancer, the contemporary management of early-stage rectal cancer, including the frequency of abdominoperineal resections, remains largely unexplored in the United States. Therefore, we assessed the utilization of neoadjuvant therapy and oncological resections in early-stage rectal cancer patients.

Study design: This is a retrospective cohort study of patients with cT1-T3N0 rectal cancer who underwent proctectomies between 2016 and 2022 in the National Surgical Quality Improvement Project proctectomy files. Multivariable logistic regression was used to identify factors associated with abdominoperineal resections and Kendall's tau statistics to evaluate clinical-pathological staging agreement.

Results: In all, 3078 patients (29.6% cT1-2N0, 70.4% cT3N0) were included with 55.3% of tumours <5 cm from the anal verge. Overall, 58.2% received neoadjuvant therapy within 3 months of surgery (30.6% for cT1-T2N0 vs. 69.8% for cT3N0, P < 0.001), and 58.6% underwent abdominoperineal resection (55.5% for cT1-T2N0 vs. 59.9% for cT3N0, P = 0.058). The adjusted odds of undergoing abdominoperineal resection were associated with increasing age (OR 1.4 per every 10-year increase; 95% CI 1.2-1.5), cT3N0 tumours (OR 1.7; 95% CI 1.1-2.7) and tumour location <5 cm from the anal verge (OR 10.6; 95% CI 7.7-14.7). There was a weak clinical-pathological T staging correlation (Kendal tau coefficient 0.25; 95% CI 0.20-0.29).

Conclusion: In this large cohort of patients with early-stage rectal cancer with high rates of neoadjuvant therapy, over half of patients underwent abdominoperineal resection and one in five had a pathological complete response. These findings underscore opportunities for organ preservation in early-stage rectal cancer, suggesting that treatments typically reserved for locally advanced disease may extend to early stages with the completion of ongoing clinical trials.

期刊介绍： Diseases of the colon and rectum are common and offer a number of exciting challenges. Clinical, diagnostic and basic science research is expanding rapidly. There is increasing demand from purchasers of health care and patients for clinicians to keep abreast of the latest research and developments, and to translate these into routine practice. Technological advances in diagnosis, surgical technique, new pharmaceuticals, molecular genetics and other basic sciences have transformed many aspects of how these diseases are managed. Such progress will accelerate. Colorectal Disease offers a real benefit to subscribers and authors. It is first and foremost a vehicle for publishing original research relating to the demanding, rapidly expanding field of colorectal diseases. Essential for surgeons, pathologists, oncologists, gastroenterologists and health professionals caring for patients with a disease of the lower GI tract, Colorectal Disease furthers education and inter-professional development by including regular review articles and discussions of current controversies. Note that the journal does not usually accept paediatric surgical papers.
